I have been kicking the idea around about trying a pond for a while now. Everything seems so easy from brochures etc. But there is no mention about what happens to the fill that is removed from the pond. This seems as if it would be a time consuming portion of the job if I have to haul it off. If it stays there, how do you keep the berm from being 2 ft tall? an 11x16 will produce a lot of fill.
